Changelog

This release upgrades the base OSS version from v1.4.16 to v1.4.17, bringing denylist model support, numerous streaming and provider fixes, and WebSocket concurrency safety. On the enterprise side, the Datadog span type for LLM calls is updated to llm.call for correct Datadog LLM Observability categorization.
